Abstract

Science learning requires direct experience in order to develop the ability to explore and understand the natural surroundings scientifically. So far in elementary school at Bukittinggi, the process of learning science only memorizes facts, principles or theories. In science learning, students are not involved in finding or applying their own ideas and they do not instill the values contained in the learning. The science learning process in classroom is not yet fully in accordance with the demands of the curriculum. The teacher provides more material in the textbook without relating it to students' daily problems that are in accordance with the material, thus causing less interesting in learning. The teacher also has not actively involved all students in learning and emphasizes learning only on students who are smarter. The purpose of this study was to increase the activity and learning outcomes of science learning by using a problem-based learning model in SDN 11 Aur Kuning Bukittinggi, West Sumatra. This classroom action research was conducted in 2 cycles with the research subjects of grade IV students with totalling 25 people. The research data were collected through observation and tests. The effectiveness of actions in each cycle from the results of observations and tests is described and then reflected to take corrective action in the next cycle. In science learning, students' learning activities were observed, namely: visual activities, oral activities, writing activities, motoric activities and emotional activities. The research findings show that the problem-based learning model can increase student activity and learning outcomes.

Abstract

Indonesia has local varieties of citrus that are no less than imported citrus, especially in terms of fruit freshness. However, people are more interested in the color of citrus peel so people prefer imported citrus to local citrus, especially in Sumatera. Therefore, it is necessary to carry out efforts to conserve and improve the characteristics of these citrus to improve their quality through plant breeding. This study aims to optimize DNA isolation methods for citrus fruit samples with Chelex-TE and to determine the genetic profile of local Sumatera citrus and imported citrus using the genotyping RAPD. The samples used were several local citrus in Sumatera (Citrus Siam Mountain Omeh, Citrus Madu, Citrus Keprok Maga, Citrus Keprok Brastepu and Citrus Pasaman) and imported Citrus (Citrus Sunkist, Citrus Clemengold, Citrus Murkot and Citrus Wokam). DNA was isolated using the 10% Chelex-TE method which was optimized for several parameters such as grain size, fruit skin and leaves. RAPD was performed using 10 RAPD primers. The results showed that the optimum 10% Chelex Chelex-TE isolation method was a sample size of 1 grain. The amplification of local Sumatran citrus and imported citrus using 10 single primers produced polymorphic bands. The value of jaccard's similarity indicates that the five samples of Sumatera local variety of citrus and imported citrus have high genetic variation.

Abstract

Asthma is a disease defined as chronic inflammation of the airways which is characterized by recurrent coughing and shortness of breath. Dermatoglyphs are the appearance of tendrils and tendril patterns on the fingers, palms, toes and soles. Dermatoglyph is used as an aid in the detection of a number of diseases that have a strong heritable basis and is also used to detect abnormalities. This study aims to analyze and compare the patterns of dermatoglyphics in asthma sufferers and non-asthmatics on the fingertips. This type of research is descriptive research with cross sectional sampling method. Samples were taken from the student population of the Faculty of Mathematics and Natural Sciences, Padang State University as many as 100 samples of fingerprint patterns. The results obtained showed that there was a significant difference in the number of arch fingerprint patterns of asthmatics compared to normal individuals. Seeing this significant difference in numbers indicates a possible link between fingerprint patterns and asthma phenotypes.

Abstract

Dermatoglyphics is a science that studies fingerprint patterns that can be inherited genetically. Fingerprint patterns can be divided into three patterns, arch, loop, and whorl. Observation of fingerprints is used to determine fingerprint patterns and the relationship between these patterns and the fields of health, education, and criminology. Left-handed is a term for people who predominantly use their left hand as their main hand to carry out daily activities. This research aims to determine the relationship between fingerprint patterns and individuals who tend to carry out activities with the left side of their body (left-handed). The type of research carried out was descriptive research with a cross-sectional sample collection method. The sample was taken from the 2019-2022 student population of the Faculty of Mathematics and Natural Sciences, Padang State University, totaling 100 individuals. The samples were taken in November and December. This research was carried out at the Genetics and Biotechnology Laboratory, Faculty of Mathematics and Natural Sciences, Padang State University. The results of this study show that the dominant fingerprint pattern found in the left-handed individual phenotype is 16 fingerprint patterns, while normal individuals have 5 arch fingerprint patterns. This shows that there is a link between the phenotype of left-handed individuals and dermatoglyphics.

Abstract

The mitochondrial genome is useful for identification because the mutation rate of mtDNA is higher than nDNA. Previous studies have carried out many analyses on the mitochondrial genome of several species, the Chaetodontidae group. Fish in this group are biological indicator fish of coral reefs, so their molecular characteristics must be enriched to conserve these fish. This article aims to review several forms of the mitochondrial genome of the Chaetodontidae group of species, including: Chaetodon speculum, Chaetodon octofasciatus, Chaetodon wiebeli, and Heniochus chrysostomus. Data were collected qualitatively by reviewing previous research articles related to the Chaetodontidae mitochondrial genome. The review focused on the characteristics of each species' mitochondrial genome, including length, overall composition, tRNA, and non-coding region. Each species exhibits various features of the mitochondrial genome and is mapped in its phylogenetic analysis.

Abstract

Science education in schools faces various challenges, such as the dominance of teacher-centered lecture methods, a lack of integration between theory and practice, and limited learning facilities. These issues hinder students from developing critical thinking, collaboration, and adaptability to modern demands. This study aims to develop a Problem-Project Based Learning (P2BL) model as a solution to address these challenges. The model integrates the strengths of Problem-Based Learning (PBL) and Project-Based Learning (PjBL) to create contextual, practical learning experiences that encourage critical thinking among students. A Research and Development (R&D) approach with the ADDIE framework is employed to ensure the systematic development of the model. The P2BL model consists of five main components: syntax, reaction principles, social system, support system, and instructional as well as accompanying impacts. The syntax of this model includes stages such as problem definition, experimentation, planning, presentation, and evaluation, supported by multi-directional interactions between instructors and students, as well as collaboration among students. The research findings indicate that implementing the P2BL model enhances academic abilities, practical skills, and the development of attitudes such as teamwork, responsibility, and time management. With its relevance to the demands of the Industrial Revolution 4.0 era, the P2BL model offers a more interactive, effective, and adaptive learning alternative to improve the quality of Science education in schools.
